Nagios Integration

Nagios is a powerful, highly extensible open source tool for monitoring network hosts and services. The core Nagios software package will typi- cally be installed on a server or virtual server - the central Nagios server.

ECS0016 gateways operate in conjunction with a central/upstream Nagios server, to provide distributed monitoring of attached network hosts and serial devices. They embed the NSCA (Nagios Service Checks Ac- ceptor) and NRPE (Nagios Remote Plugin Executor) addons – this allows them to communicate with the central Nagios server, eliminating the need for a dedicated slave Nagios server at remote sites.

The ECS0016 supports basic distributed monitoring. Even if distributed monitoring is not required, the ECS0016 gateways can be deployed lo- cally alongside the Nagios monitoring host server, to provide additional diagnostics and points of access to managed devices.

StarTech.com’s MetaConnect for Nagios extends the capabilities of the central Nagios server beyond monitoring, enabling it to be used for cen- tral management tasks. It incorporates the MetaConnect client, enabling point-and-click access and control of distributed networks of ECS0016 gateways as well as their attached network and serial hosts, from a central location.

Please note: if you have an existing Nagios deployment, you may wish to use the ECS0016 gateways in a distributed monitoring server capacity only; if this is the case, skip to the section titled Enable Nagios on the
